TL;DRAn option to switch off hand crafting for specific items would be great.
What ?WHAT do you suggest?
For example, I have a production for yellow belts, which I want to use to create red belts. But when I hand craft some red belts, it consumes either the yellow belts I have with me or crafts them on the fly (if I have the ingredients). I created the yellow belt assembly machine to use that items for crafting red belts, so I don't want to waste my iron plates or whatever is required for yellow belts.
Idea would be to mouse over an Item in your inventory crafting part (the right side of the inventory) and press a hotkey (alternative, you can use 3rd mouse button to set blocking on/off). A red led in the corner of that Items (or a red frame around the item) indicates that it is blocked for hand crafting.
Why ?WHY do you think it increases the value of Factorio as a game?
I like the challange, to build a assembly machine for everything relevant, but I don't want to be forced all the time to go for an assembly machine. Above idea, would allow me to configure it to my needs and is flexible, so I can switch it on/off at any time. It gives me a better control over the items in my inventory and how they are used.
What do you think?
